Scientists are now using artificial intelligence to decode dinosaur footprints in a way that was never possible before. With just an image, this new tool can reveal patterns that were previously easy to miss. For decades, fossilized footprints have been one of the most intriguing yet frustrating clues in paleontology. These traces capture moments of prehistoric life, showing how dinosaurs moved, behaved, and interacted with their surroundings, yet identifying their makers has often remained uncertain.
The difficulty comes from the nature of the evidence. Footprints are frequently altered by erosion, shifting sediments, and incomplete preservation. This makes precise classification difficult even for specialists and has led to disagreements within the scientific community.
A Mobile Tool Bringing Fossil Analysis To Everyone
At the center of this innovation is DinoTracker, a smartphone application that allows users to upload photos or sketches of dinosaur footprints. Within moments, the system analyzes the image and suggests which type of dinosaur may have created the track.
According to the latest research published in Proceedings of the National Academy of Sciences, the tool is designed for both professionals and the general public, making fossil identification more accessible than before. This marks a shift from traditional methods, where interpretation relied heavily on expert judgment and limited datasets.
Footprints remain a key source of information in paleontology. They capture details of movement, posture, and behavior, yet interpreting them has long divided scientists working from the same material.
Fossil Analysis Powered by AI Training
To overcome these limitations, researchers from the Helmholtz-Zentrum research centre in Berlin, working with the University of Edinburgh, developed an AI system that learns footprint variation through data rather than predefined labels.
According to the same source, the model was trained on nearly 2,000 real fossil footprints along with millions of simulated examples. These simulations reproduced natural distortions such as compression and shifting edges, helping the system recognize patterns in imperfect conditions.
The AI focuses on eight main characteristics, including toe spread, heel position, and how weight is distributed across the foot. By analyzing these features, it compares new footprints with known examples and estimates the most likely trackmaker.
The Dinosaur–Bird Connection Just Got Clearer
When tested, the system achieved about 90 % agreement with expert classifications, even in complex or disputed cases. This suggests the AI can serve as a reliable support tool in paleontological research. One of the most striking findings involves footprints dated to more than 200 million years ago. The AI identified similarities between certain dinosaur tracks and the foot structures of both extinct and modern birds.
According to statements from the research team, this could mean that birds, or bird-like dinosaurs, appeared tens of millions of years earlier than previously believed. Another explanation mentioned in the source is that some early dinosaurs developed bird-like feet independently.
The system also helped reinterpret footprints discovered on the Isle of Skye in Scotland. Formed around 170 million years ago, these tracks had puzzled scientists for years. The analysis suggests they may belong to early relatives of duck-billed dinosaurs, making them among the oldest known examples of this group. As reported by Professor Steve Brusatte, it could reshape how scientists study ancient life through one of its most subtle forms of evidence.
“It opens up exciting new possibilities for understanding how these incredible animals lived and moved, and when major groups like birds first evolved. This computer network might have identified the world’s oldest birds, which I think is a fantastic and fruitful use for AI.”
